CRANKLES S MECHANI SM Filed 001:. 5. 1929 I NV ENTOR V/cfar ,7. 1447500 Patented July 14, 1931 UNITED STATES PATENT OFFICE VICTOR R WILSON, OF MELBOURNE, AUSTRALIA, ASSIGNOR TO MICHELL-CRANIILESS ENGINES CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK ORANKLESS MECHANISMS Application filed October 3, 1929. Serial No. 396,975.-

This invention relates to crankless mechanism in which linear or reciprocating motion is transformed to rotary motion by means of slants or swash plates.

In mechanism of the character specified, the reciprocating elements move in a path parallel to the swash plate shaft and intersecting the slant or swash plate.

This invention has for its object to provide a slant or swash plate, so constructed and arranged as to permit the removal of the reciprocating elements from the mechanism by movement in the direction of the axis of reciprocation.

Further objects of the invention will appear from the following specification taken in connection with the drawings, which form a part of this application, and in which Fig. 1 is a sectional elevation of a slant or swash plate and the reciprocating elements coacting therewith;

Fig. 2 is an elevational view of the swash plate taken at right angles to Fig. 1; and

Fig. 3 is an elevational view, partly broken away, of the swash plate, the removable segment being removed.

The invention briefly described consists of a swash plate or slant having a removable peripheral portion or segment Further details of the invention will appear from the following description.

In the embodiment of the invention illustrated, there is shown a shaft 10 having a swash plate 11 thereon, the shaft being mounted in suitable bearings 12 and 13.

The peripheral portion of the swash plate is engaged by a pair of slipper pads 14 and 15 carried by a yoke 16 which connects piston rods 17 and 18 carried by pistons 19 and 2 mounted in cylinders 21 and 22.

The crankless mechanism described may be used as an engine or as a pump and the reciprocating motion of the pistons is transmitted to the shaft through the slipper pads and swash plate in the usual well known manner. 7

In order to facilitate the removal of the reciprocating elements, the swash plate. has a removable portion or segment 25 adjacent 50 the periphery thereof and of sufficient size to permit the withdrawal of the reciprocat ing elements in a direction coinciding with the path of movement of the elements. In the particular form ofthe invention shown, the swash plate has a peripheral arcuate recess 26 provided with an arcuate groove 27 and the segment 25 is shaped to fit into the recess 26 and is provided with an arcuate tongue 28 adapted to fit in the groove 27. The segment ma be secured to the swash platein any suita le manner as, for instance, by bolts 30 and 31. The outer periphery of the segment 25 is preferably recessed, as shown at 32, to receive the heads of the bolts 30 and 31.

When the reciprocable elements are to be removed, the segment 25 of the swash plate is removed from the remaining portion of the swash plate and the recess 26'is alined with the reciprocating elen1ents. The elements can then be withdrawn in the direction of their reciprocating movement without engaging the swash plate or hindrance thereby.

Although one specific embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes inthe construction and in the arrangement ofthe various cooperating parts maybe made withoutdeparting from the spirit or scope of the invention, as expressed in the following claims.

What I claim is:

1. In mechanism of the character de-' ing the opening.

3. In mechanism of the character described, a swash plate having a portion of its peripher removably secured thereto, said removab e portion having a tongue and groove connection with the remaining portion of theswash plate.

4. In mechanism of the character described, a swash plate having a removable segment, said segment having a tongue and groove connection with the remaining portionof the swash plate.

Y 5. A swash plate having a pair of substantially flat faces and having a removable segment provided with flat faces, and means for marntammg the faces of the segment in the planes of the faces of the remaining portion of the swash plate.

6. A swash plate having a grooved recess in the periphery thereof, and a segment secured to said recess and having a tongue fitting the groove therein.

7. A swash plate having an arcuate' grooved recess in the periphery thereof, and a segment secured to said recess and having atongue fitting the groove therein.

8. In mechanism of the character described, a swash plate having a portion of its periphery extending from one face to the other thereof and removably secured thereto, and means disposed inwardly of the periphery of said swash plate securing said removable portion thereto.

9. In mechanism of the character de scribed, a swash plate having a removable segment extending from one face to the other thereof, and means disposed inwardly of the periphery of said swash plate securing said segment thereto.

10. A swash plate having a removable portion. said portion and the remaining portion of the swash plate having interfitting parts for preventing relative movement between the removable portion and the remaining portion of the swash plate, and means for securing the removable portion to the remaining portion of the swash plate.
